Re: [ARSCLIST] Interesting WSJ Article on when libraries should discard their holdings.
Yes, as power supply decoupling, but there the values are less critical.
Caps in analog gear, you find them in a lot of audio circuits in
addition to power supply decoupling. Often in old audio gear, where the
caps in the audio circuits dried out or aged, the low end would fade
away due to the caps lowering there value. That said, I think that
direct coupled audio has been getting much more common in any case...

On the contrary, capacitors are crucial in all digital circuits. They
provide the immediate power supply to the logic chips.
